Federal 5.56x45mm NATO MK318 MOD 0 SOST(Special Operations Science and Technology) ammunition with a 62 grain "barrier blind" open tip match bullet, 3000 fps, 20 Round Box

This new SOST round from ATK was designed for the USMC as a supplemental round to M855 green tip with more desirable terminal characteristics. Designated as MK318 MOD-0 the round was designed as a barrier defeating round with superior penetration and better ballistic stability when shooting through glass, car doors and other barriers where other rounds simply bounce off. It was engineered after the Marine Corp identified issues with the M855 round. MK318 utilizes a 62 grain open tip boattail match bullet with a lead core and reverse copper jacket creating the open tip.

"I have found it to be VERY accurate (groups are about HALF the size of M855 at 50 yards). It fragments within 1cm of entering soft tissue, but the base of the bullet will still punch through bone and intermediate barriers. It fragments more consistently, quicker, and bigger than M855....AND the fragmentation range from a 14.5\" barrel is extended by almost 100 yards (est. frag range of 160 yards). Outstanding. Full sealant around case mouth and primer. Bullets were seated to a very consistent depth (crimped into the first 'driving band'). Gonna be a great hog round!"

"I got 500 rounds of these and have been very impressed. They are almost as accurate as the BVAC 75gr Tactical (using Hornady's T1C 75gr otm bullet) out to 100 yards. Barrier blind is right....already shot it through 2x4's (longways) and it just cuts the entire board in half. Same thing with two 2x4's end-to-end (arranged as if they were a 2x8). Really impressed. Downed one small hog, a 90lb-er, and he was DRT. NO running and only a little kicking and squealing. Inside looked a lot like the 75rg hornady round...which is to say it looked shredded. BUT, the Mk318 had an exit hole, where the 75gr did not. Highly recommended."
